Heroic Extremists are heroes who are similar to Anti-heroes, but in revenge, they are way more extreme in pursuit of their heroic goals.

These heroes are primarily focused on a revolution or a social change that is noble and meant to benefit society, they are even willing to use weapons of mass destruction, torture, or even mass killings to achieve these goals and to even stop a villain's scheme.

Many of them tend to straddle the line between good and evil, with some going so far as to fall to the dark side. These characters can do heroic, noble and selfless deeds in order to stop their rivals and enemies from continuing in horrible acts, but their acts of vengeance against their rivals and villains, are explicitly shown by taking things deeply to extremes and it can be rather questionable actions of theirs.

Note: Pure of Heart heroes & Near Pure Goods can never be extremists because extremists are often willing to commit acts that aren't very good when it comes to being heroes and tend to be very unpredictable with their morals.
